Knot colouring polynomials
MICHAEL EISERMANNWe introduce a natural extension of the colouring numbers of knots, called colouring polynomials, and study their relationship to Yang-Baxter invariants and quandle 2-cocycle invariants.For a knot K in the 3-sphere, let π K be the fundamental group of the knot complement ޓ 3 K , and let m …
